I was working on putting in dividers (acrylic ones) and was putting in the back piece. It would fit, so i just was seeing if it wasnt in the slot, and the side panel to my tank just cracked rather largely >_>

Can i put silicone over this on both sides to seal it, and then perhaps paint it black on the outside so its not noticable?

....crap thats what i thought...i was going to put the silicone on both sides, because it would be hidden by the divider, and painting it would hide it too...but i guess i will just go get another tank...i wanted two anyways down the road....
